The German brand Grimme is familiar to domestic consumers, first of all, for its agricultural implements. The equipment produced under this brand has earned a good reputation. It simplifies the harvesting process, which is necessary when growing crops on an industrial scale.
Types of units from Grimme:
- bunkers;
- elevator;
- self-propelled
The most popular are bunker and elevator machines. They are attached to other units and can perform direct or lateral digging.
German-made Grimme machines are distinguished by high productivity, ease of potato peeling and long-term continuous operation. Various separating devices can be connected to the equipment, which expand its functionality.
Features of Grimme combines
Potato harvesting units are in demand because they cope with a wide range of jobs. These machines are used to harvest potatoes, separate tubers from tops, and separate various impurities.
The combine has a special digging design with rollers for removing tops and depth settings, with two knives and spring-loaded cutting discs. The angle of inclination of the discs is adjustable.
Specifics of the combine operation:
- A layer of soil of the specified thickness is removed;
- The vegetable along with the tops is delivered to the sifting mechanism;
- The tops are separated, the potatoes are cleared of soil and leaves, the crop is sorted by size;
- The vegetable falls into a hopper with a moving bottom;
- The potatoes are unloaded from the bunker onto a transport vehicle.
The advantages of the Grimme potato harvester are the following:
- Optimal cleaning of tubers;
- Good visibility when driving;
- Tilt leveling functions;
- Large optional set and the possibility of individual selection of components;
- Maximum quiet operation of the unit.
It is not always easy to purchase components in the event of a breakdown. And the cost of this product is relatively high.
Main characteristics
The determining parameters when choosing potato harvesters are its type, the number of rows of knives, the features of digging, and the power of the equipment. A large number of rows of diggers allows for faster processing of the site. High engine power allows you to speed up the process of moving across the field. The volume of the bunker is also important: its large capacity allows for infrequent unloading of collected root crops. The Grimme SL 800 model is optimal in all respects (has good power, productivity, low price), the characteristics of which allow you to carefully and efficiently harvest the crop without damaging it.
Technical description of the Grimme combine
Before purchasing, it becomes mandatory to study its features and technical data. Careful selection will determine the need to purchase a modification. For example, the BR 150 Grimme trailed combine is equipped with a 4.5-ton bunker and is capable of subsequent unloading to a height of up to 3.4 m. It can be connected to a tractor with a power of 80 hp or more. for example MTZ-1221. Includes three conveyors and 2 topping shafts. The operating speed is 3-5 km/h. Equipped with two rows of knives, suitable for small and medium-sized areas.
Design Features
The operating principle of the models is identical, only the type of unloading of collected root crops differs. Additionally, we can highlight the ability of the equipment to work without auxiliary vehicles (self-propelled) or to be used as a supplement (trailered).
Raising and feeding the potatoes to the peeling mechanisms is done using ridges.
They go deep into the soil by approximately 15-20 cm. Next, the conveyor sifts out the soil, and when moving the potatoes, the residual tops are separated. All removed sprouts are thrown away, and the root crops are transferred either to the equipment bunker or transported to a separate truck. Productivity is determined by the capacity and frequency of unloading of collected vegetables. For example, the Grimme SE 75 40 model has a hopper capacity of 4 tons. This modification is suitable for long-term use and ensures quick harvesting.
Pros and cons of technology
The main advantage of the technology is the ability to quickly clean large and medium-sized fields. Careful harvesting of root vegetables makes it possible to obtain high income from harvested undamaged vegetables. Other advantages of using potato harvesters include:
- ease and simplicity of control;
- economical fuel consumption;
- full automation of the harvesting process;
- Possibility of use in areas with any soil;
- good productivity (from 0.7-1 and above hectares per hour).
The only drawback of the equipment is their high cost and maintenance. Due to reliable internal systems, each model is determined by the high price of the Grimme SE 150 60 combine harvester, for example, it costs about 8 million rubles. Repairing such models requires significant costs, and scheduled maintenance must be carried out more often than other modifications. Special attention should be paid to the mechanisms that transfer root crops to the bunker. Contamination of passages or soil adhesion will lead to premature failure of the device.

Design and operating features
The design of Grimme SE 150 60 is represented by the following main elements:
- chassis;
- excavation sections with ridge drums and separating discs;
- main transporter;
- tops separator;
- screening conveyors;
- sorting conveyors;
- transporter of impurities;
- stone catcher;
- sorting table;
- loading conveyor;
- storage hopper with a movable bottom.
Since the late 1900s, the manufacturer has offered this model in 2 chassis options: drive wheels with hydrostatic drive or driven wheels. Modifications without a drive are more popular. Since the beginning of production, the chassis has been modernized several times; the latest versions have a wider axle. A single knuckle steering system is available for both chassis variants. 600/55-26.5 tires are standard on the combine, but 710/45-26.5 and 800/45-30.5 tires are also available.
The combine trailer is made using a K-80 type ball hitch. The drawbar behind the hitch was modernized several times, increasing in size. Since 2012, the model has been equipped with a Bondioli and Pavesi driveshaft; previously a Walterscheid driveshaft was used. An optional gearbox with 3 gears is available. Since 2001, the final drive has not been equipped with drive chains. The inspection table and separating mechanisms operate hydraulically.
The standard gripping section is 1500 mm wide and does an excellent job of digging up vegetables. The screening channel has a robust design and is used for initial screening.
After the first and second elevators there is a needle conveyor where the vegetable mass is supplied. Since 2010, this element has been unified for all models of the brand, so there are no problems with its replacement. Several types of separating devices are available for Grimme SE 150 60:
- The UB type is designed as a finger conveyor with a cleaning roller and infinitely variable hydraulic adjustment. Used on any type of soil with a limited number of stones and lumps;
- The SB type is a brush conveyor with infinitely variable hydraulic adjustment and a passing conveyor used for impurities. This separating device is recommended for use on soil with a lot of stones;
- NB-type – cleaning roller, infinitely hydraulically adjustable. A similar device is used on light soil without lumps and stones.
After completing the basic operations, the vegetable mass enters the hopper, which is optionally equipped with a rubber lining to optimize filling. Thanks to the addition, the factory capacity of 6000 kg can accommodate up to 6300 kg. A larger hopper with a capacity of up to 7,500 kg is also available. Since 2005, the manufacturer has been offering a special reloading hopper. In the standard version, the hopper has lifting arms.
The combine is controlled via a CAN bus; ISOBUS control is available upon request. In the basic version, the model can be controlled using the CCI200 and CCI100 terminals. However, the most common is the VC50 terminal, equipped with a touch keyboard, the feature of which is considered to be a direct mode with the possibility of free programming. To operate the balancing system and bridge, a GBX860 remote control with 2 cross levers is used. The hopper on the left is controlled using the GBX870 remote control. Quite convenient is the Visual Protect option, which, if there are problems with the equipment, automatically transfers the surveillance screen to the appropriate camera.
